    Lets see! Haven't done these except for RA snorkel Protecting warranty. Seams like ultimate for 4B11 engine, day to day motoring. Other then a turbo is :- RA snorkel, 4-2-1 extractor, high flow cat, 2.25 or 2.5 inch piping, may be 1 or 2 resonators for peace of mind, and a free flow matching muffler.

    Above, knowledge based on info gained from analasist of various forums over time. According to expert tuners 2.25 or 2.5 inch exhaust much of a muchness. Original air filter is just fine.
    4-2-1 or 4-1 extractors. 4-1 more power suite street racing. 4-2-1 better torque and low down grunt for legal speed limits! and power where you need it for day to day driving.

    Bingo!!!!! Wonder what power and torque figures will show up. Maybe a dyno test, can give us some idea!

    Any info on blanking off EGR and results gained or lost! Understand some lancers don't have one!

    EGR on a turbo would be mighty hot!!??:imp:

    There's a book called "performance exhaust systems" by Mike Ravrigian
    Have a read of that sometime.
    Or just Goto the Lukey Australia web site and read their tech specs for exhaust cos what the book said and what Lukey said is the same anyhow.
    Extractors with cat back 2.25 inch , ecu tune , RA snorkel , high flow air cleaner , 4G69 TB , and wrap everything under the bonnet with either gold heat reflection tape or exhaust wrap to keep the heat down , drop on a RA bonnet to get rid of the heat and your on a winner
